RANDOM FLUCTUATION IN AN ELECTRICAL SIGNAL

Noise (telecommunications); Random noise; Line noise; Electrical noise; Noise (physics); Noise (electronic); Noise (signal); Electronic noise; Signal noise; Channel noise; Hiss (electronics); Electronic circuit hiss; Coupled noise; Transit-time noise

line noise

<communications> 1. Spurious characters due to electrical noise in a communications link, especially an EIA-232 serial connection. Line noise may be induced by poor connections, interference or crosstalk from other circuits, electrical storms, cosmic rays, or (notionally) birds crapping on the phone wires. 2. Any chunk of data in a file or elsewhere that looks like the results of electrical line noise. 3. Text that is theoretically a readable text or program source but employs syntax so bizarre that it looks like line noise. Yes, there are languages this ugly. The canonical example is TECO, whose input syntax is often said to be indistinguishable from line noise. Other non-WYSIWYG editors, such as Multics "qed" and Unix "ed", in the hands of a real hacker, also qualify easily, as do deliberately obfuscated languages such as INTERCAL.

Noise (electronics)

In electronics, noise is an unwanted disturbance in an electrical signal. Noise generated by electronic devices varies greatly as it is produced by several different effects.

Brownian noise

THE KIND OF SIGNAL NOISE PRODUCED BY BROWNIAN MOTION

Brown Noise; Brown noise; Red noise; Random walk noise; Red-noise

In science, Brownian noise, also known as Brown noise or red noise, is the type of signal noise produced by Brownian motion, hence its alternative name of random walk noise. The term "Brown noise" does not come from the color, but after Robert Brown, who documented the erratic motion for multiple types of inanimate particles in water.

Noise (electronics)

In electronics, noise is an unwanted disturbance in an electrical signal.^: 5

Noise generated by electronic devices varies greatly as it is produced by several different effects.

In particular, noise is inherent in physics, and central to thermodynamics. Any conductor with electrical resistance will generate thermal noise inherently. The final elimination of thermal noise in electronics can only be achieved cryogenically, and even then quantum noise would remain inherent.

Electronic noise is a common component of noise in signal processing.

In communication systems, noise is an error or undesired random disturbance of a useful information signal in a communication channel. The noise is a summation of unwanted or disturbing energy from natural and sometimes man-made sources. Noise is, however, typically distinguished from interference, for example in the signal-to-noise ratio (SNR), signal-to-interference ratio (SIR) and signal-to-noise plus interference ratio (SNIR) measures. Noise is also typically distinguished from distortion, which is an unwanted systematic alteration of the signal waveform by the communication equipment, for example in signal-to-noise and distortion ratio (SINAD) and total harmonic distortion plus noise (THD+N) measures.

While noise is generally unwanted, it can serve a useful purpose in some applications, such as random number generation or dither.

Pronunciation examples for line noise

1. executable pseudocode and if that's the case, then Perl is executable line noise. But, yeah,
